What type of solution is typically applied to resistant hair before rodding in permanent waving?

1. Neutralizing solution

2. Wave solution

3. Conditioning treatment

4. Moisturizing lotion

The correct answer is: Wave solution

The application of a wave solution to resistant hair before rodding in permanent waving is designed to break down the disulfide bonds in the hair's structure. This is crucial because resistant hair tends to be coarser and more difficult to alter chemically than other hair types. The wave solution contains thioglycolic acid or its derivatives, which effectively penetrate the hair shaft and soften it, allowing the hair to better conform to the shape of the curlers used during the perming process. Using a wave solution specifically aims to ensure that the chemical reaction occurs effectively, providing the best chance of achieving the desired curl pattern. This preparation step is essential to ensure that, after processing, the hair will hold the curl and not revert to its original, straighter state. Other products like neutralizing solutions, conditioning treatments, or moisturizing lotions serve different purposes and do not fulfill the necessary role in processing resistant hair for perming.
